Abstract: To achieve high thermal stability, the laser is constructed from discrete assemblies (R, E, V1, V2), using a modular design which assemblies are fixed alone and without any mutual mechanical coupling on a central supporting plate (T), the supporting plate and the resonator (R) having thermal coefficients of expansion which are approximately or roughly the same. In this way, a simple construction is also achieved, together with easy production and assembly possibilities. The invention is suitable for gas lasers constructed using the "sealed-off" technique, particularly for CO2 lasers. <IMAGE>

Abstract: In a four level FSK optical communication apparatus, signal light (3) which is modulated in FSK with information is transmitted through an optical transmission line (4). The signal light is detected (8) in an optical heteroclyne system by using local oscillation light (6), thereby producing intermediate frequency band signal which is then demodulated. A detection system comprises first and second delay (20, 20B) detection circuits. In the first detection circuit, the intermediate frequency band signal is divided into first and second signals. The first signal is delayed by a delay time (15), and then mixed (17) with a second signal which is not delayed to produce first delay detection signal. In the second delay detection circuit, one of the first signal delayed and the second signal not delayed is shifted in its phase by π/2. Then, signal having the phase shift of π/2 and signal having no phase shift are mixed (18) to produce second delay detection signal. Thus, the demodulation of four level FSK modulation signal is performed.

Abstract: Method and apparatus is disclosed which inexpensively and conveniently tests ordinary twisted-pair (TP) telephone wires (20) installed in a premises for suitabily interconnecting elements of a high-speed local area network (LAN). The method eliminates the need to trace the wires or to disturb them in any way. Signals are transmitted onto the near end of the TP wires and are reflected from their open far ends. The received reflected signal from a selected TP wire is compared against the transmitted signal and the TP wire is deemed satisfactory if the comparison shows a bit error rate (BER) less than a predetermined upper limit. Preferably the method is used in conjunction with a directional coupler (34) connected to a transceiver (32) which conducts the signal generated by the transceiver onto the TP wires and conducts the reflected signal from the selected TP wire to a receiver portion of the transceiver.

Abstract: On a transmitting side, a digital video signal comprising respective pixel samples (each of which may include eight bits) is received, and a set of elementary pixel samples (ⓞ) determined from the received pixel samples at a predetermined rate are transmitted. The values of respective subject pixel samples (o, □, Δ, x) other than the elementary ones (ⓞ) are predicted, and respective predictive errors (ε) of the predicted values are detected from present values of the received pixel samples. First flags are then generated individually for each subject pixel sample whose predictive error (ε) is greater than a threshold value (TH), and second flags are generated individually for each subject pixel sample whose predictive error is less than or equal to the threshold value. The present values of the subject pixel samples having the first flags are transmitted, and compressed data (including the second flags) is transmitted for the subject pixel samples having the second flags. On a receiving side, values of the subject pixel samples represented by the compressed data with the second flags are predicted, and the subject pixels are interpolated with pixel samples having present values equal to the predicted values. A decoded video signal, including the transmitted elementary pixel samples, the respective subject pixel samples having the first flags, and the respective interpolated subject pixel samples, is then outputted.

Abstract: This relates to a sealing head for sealing lids to cartons. The sealing head (10) is provided with suction heads (26) or cups for receiving a lid from a lid supply and depositing such lid in position on a carton which is mounted in a nest. The sealing head is provided with a seal member (56) which forms the seal with a nest carrying a carton so that a vacuum may be drawn within the nest both within and around the carton. Thereafter, the sealing head provides an inert gas, such as nitrogen, to fill the carton with the inert gas, after which a support further sealing head moves the sealing head down further so that a lower edge of a projecting induction heating coil (24) will clamp a lid against a carton and effect a heat bonding of the lid to the carton. The sealing head is self contained and has a fitting including a plurality of electrical prongs (136,138) and fluid line sockets (140,142,144) for coupling the sealing head to a receptacle. Finally, the induction heating coil of the sealing head is of a special configuration so as to compensate for a pull tab carried by the lid, which lid is generally oval to match the oval carton. The outline of the coil deviates slightly from the oval shape so as to provide a seal which has a starting point to initiate peeling of the lid from the carton. Further, this starting point is aligned with the pull tab and there are current compensating pins (186,188) carried by the coil to compensate for the metal within the pull tab.

Abstract: In humid atmospheres (e.g., 40% relative humidity or above) solutions of 2,2-bis(3,4-dicarboxyphenyl)hexa­fluoropropane dianhydride/2,2-bis[4-(aminophenoxy)phenyl]­hexafluoropropane polyamic acid polymers or polyimides tend to be unstable in the sense that during spin coating operations undesirable precipitate formation occurs on the rotating surface of the wafer. The result is the forma­tion of unacceptable coatings due to their irregularity and lack of uniformity. Described are compositions especially adapted for use in spin coating wafers of semiconductive materials, which comprise solutions of these polyamic acid or polyimide polymers in a solvent containing at least 10% of a cycloaliphatic ketone (e.g., cyclohexanone) or mixture of cycloaliphatic ketones, such that the solution (a) contains on a weight basis from 5% to 40% of the polyamic acid or from 5% to 50% of the polyimide, and (b) does not undergo precipitate formation during spin coating in an atmosphere of up to at least about 55% relative humidity.

Abstract: A method and an apparatus for making prints from a photographic film (18) with DX codes including start and end bits in association with frames in which the photographic film is intermittently moved in one lengthwise direction by a pulse motor (23) so as to place the photographic film in an exposure position frame by frame in an inspection process. If a frame is incorrectively placed in the exposure position, the pulse motor (23) is finely controlled to rotate for correctively positioning the frame. In the inspection process, the information marks are counted before a frame reaches the exposure position and drive pulses applied to the pulse motor after the information mark of the frame is detected are also counted. These counted values are memorized as position data for the frame in a memory. In a printing process, the photographic film is moved either in the same or the opposite direction to automatically, accurately place each frame to be printed in the exposure position by controlling the pulse motor based on the position data for the frame retrieved from the memory.
